This invention relates to new and useful irnprovements in presses and has particular relation to a press of general utility `in machine shops, manufacturing establishments, etc.

The objects and advantages of the invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawings wherein a satisfactory embodiment ofthe invention is shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

In the drawings:

Fig. 1 is a side elevational view of the upper portion of the press of the invention onlythe supporting legs or structure for the bed being omitted; I V Y Fig. 2 is a view partly in section and partly in side elevation to show details of construction;

Fig. 3 is a top plan view of the entire press;

Fig. 4 is an enlarged side elevational view of a portion of the head showing a locking plunger and some associated parts;

Fig. 5 is an enlarged side elevational view taken as along the plane of the line 5-5 of Fig. 2; and

Fig. 6 is a detailed sectional view taken as along the line 6--6 of Fig. 2.

The present invention has many uses, such as for shearing punches and dies in a tool room, for

separating punches and die holders, for Vassembling and aligning punches and dies, for use as a straightening press, and for use as an arbor press. Thus, it will be seen that the press is of 4 Claims. (Cl. 164-101) rather general use and constitutes quite an asset A in any tool room, although for some purposes it may be used in actual production work.

Referring in detail tothe drawings, the press of the invention is shown as including a bed Ill which may be formed with or attached to any suitable base or supporting legs or the like. Disposed over the bed I0 is a yoke-like structure generally designated I I and shown as somewhat shown as passing through foot portions I'I on the arms I2 and I3 and then entirely through the bed Ill. In its upper surfacefthe bed maybe provided with any desired number of tapped holes or recesses I8 for the reception of bolts when clamping workto the bed. TheA yoke-like member IfI may `include strengthening ribs I9, as shown.

Within the upright portion I4 there is xed a sleeve 2|] vertically disposed and extending from a position within thehead I5 through to the lower end of the upright I4 and attached to such lowerend as by means of screws 2 I. Within this sleeve is a bar 22 having a keyway 23 extending chine and there mounting a relatively large diameter hand wheel 28. Threaded through the worm gear 25 is a jackscrew 29 at its lower end reduced (see Fig. 6) to provide a neck 30 and at the free end of such'neck having an integral head-like portion 3|. This head-like portion occupies a recess lin the upper end of the bar 22 and the neck-like portion 30 of the jackscrew is located in the innerend portion of a laterally opening slot 32 in such upper end portion of the bar 22. and the jackscrew, it will be apparent that such parts are adapted for relative turning movement and that they are connected for endwise movements together..

The screw 29 has a longitudinally extending keyway 33 and at the upper side of the head I5 this screw passes through a bushing 34 carrying a key 35'located in the keyway 33 of the jackscrew. At its lower end, bushing 34 includes a radial flange 36 located against the upper side of the head I5 and held against movement away from such head by means of a clamping ring 3i secured in place by screws 38.

About thebushing 34 and secured thereto by key 39 is a relatively largeA hub-like portion 40 of a large hand wheel, generally designated 4I. This hand' wheel is horizontally disposed and of a diameter extending outwardly over the vertically disposed hand wheel 28. Hand wheel 4I, at its underside and radially with respect to the hub portion 40, is providedr with Web-like portions 42 and 43, each having a socket 44 opening through its lower end.

On one side` of the head I5 there is formed or mounted a relatively thick plate-like member 45 With this connection between the bar A small plug 54 may be used for securingV the spring 48 in place. 'I'he bolt 48 is so located that then the wheel 4| is turned to present one*v of the sockets 44 above the bolt, the latter. may be manually shifted to dispose its upper end in such socket. .'Ifhis .vis las shown in-Figs; 4 andl 5 yand the bolt wlllbe manually shifted through the manipulation of the pin 49.. When the bolt is .4 against all but turning movement and therefore when rotated, acts as a nut to feed the jack screw 29, which is being held against all but longitudinal movement. The ratio in the gearing shown is such that for one revolution of the wheel 28 the screw 4is moved .one thirty-second of an inch.

From this it will be apparent that wheel 28 may be used to exert a tremendous pressure through the bar 22. In using the press of the invention, wheel 4| mayl be vrapidly rotated to shift the bar to a position where great pressure v is to be exerted. In fact, the wheel 4| may jamb in locking relation with the when 4|, bauv 53;

is held in the notch 5| and maintains the bolt elevated against casualdisplacement. When-*the bolt is pulled down into an inoperative,V position, the ball 53 may snap-intothe notch50.

Fixed to the lower end of the bar 22 is a shank.

holder, generally designated. 55; and comprising a shank portion 5'5v fixed v to thefbar 22v and a block 5l. to be clamped in place by meansV of bolts 5'9. Whenthe block 581-is tightin-.placm Vit together with the block portion. 51. maybe clampingqany shank Si) of a punchlblock 8| comprisingpart of the die set, generally designated |52-infIigr."1.v

When using the* press ofthe inventionA any work may be'mountedronthe-bed. lll.. For exam.-

ple, in Fig. 1 thev dotted lines suggest-positioning.

of a die set `on the bed. This die set may. not have been in use for some time and-to separate the blocks considerableforce will. be: needed.v

Therefore, when it is properly aligned: with the shank holder andA clamped'to the bed |50 the shank holder isy clamped tight tothe shank 60 of the punch block; Now by'operating. either .of

the wheels, 28- -or 4|-,; the. punch block; is drawn. upwardly on the pins of the die set. as tol the positionshown.

Wheel 4|v is usedl for rapidlyv moving the. bar

fed through the gears.

being held between the upper end7 of. sleeve 20 and the upper wallof thehead- I5.

The immediate result of` turningwheel 4| is to turn` the hubi 40-andthrough1the key 39y the.

bushingV 34. Through keylv.35. the said: bushing is secured to the jackscrew. vfor. turningof the latter. As the'screw turns itis-.fed longitudinally and raises or lowersthe bar 22 and thus theshank holder 55, or'any other means attached to the bar. The latter being, heldbykey 24. has

no turning movement inthe xed guide sleeve 2|).

Movement of screw 29 and bar. 22.through manipulation of the handA wheel 28 is at` a much less rate for a given movement of suchfwheel'. than when the wheel 4| is used. When` wheel. 28.- is` rotated the rlock bolt 48 is in one of the socketsv 44 so that wheel 4| is held. against. turning move.- ment and since such wheel is keyedV to. the screw 29, the latter may not rotate but may be. fedY longitudinally. Wheel 28-turns` the worm .26 and through the latter thegear 25. Such-gear sheld 76 1,966.209

A correspondingV block. 58. is adapted.

y the-bar against a piece of work. Thereafter wheel 15.

4| is secured by lock bolt 48 and the wheel 28 turnedt to apply the required pressure. It is noted that while-both wheels are of relatively large diameters, the wheel 4| extends out over and beyondrthewheel 28.

Having thus set forth the nature of my invention-,what I claim is Y 1...InK a` press, a-bed,.a yoke-like frame having itsarms secured to opposite edge portions `of said bed, said framefincluding an intermediate vertically extending. hollowportion having a head at its upper end; a bar. vertically movable in said vertically extendingv portion, a screw connected tovsaid bar but rotatablerelative thereto and extending: to-theupper side of said. head, a hand wheel: about` the upper end portion of said screw above said head, andy comprising ahub, a bushing withinand keyed to'said hub, means securing said. bushing toV said frame head. but for turning movement relative thereto, a key and-keyway connecting said bushing and said.i screw, a worm Wheel` threaded to said screw within said head, a. worm meshing with said worm gear, a hand wheel-,forA turning said.
